2012) GOLVEN secretory peptides regulate auxin carrier turnover during plant gravitropic
The primary root system is a positively gravitropic
taproot system, with lateral roots branching off the main taproot (Jones, 1993; Grobbelaar, 2004).
1], 100% of the seedlings showed some abnormality (see Table 1): severe atrophy of the stems, roots, leaves or absences of these parts; gravitropic
inversion; and necrosis of the stems, roots or leaves.
Four types of anomalies caused by extracts were identified as damaging or weakening seedling development: 1) root atrophy; 2) early secondary root development; 3) gravitropic
plant inversion and 4) root necrosis, according to Regras para Analise de Sementes (BRASIL, 2009).
Dr Kepinski said: "We have found that another growth component -- the 'anti-gravitropic
offset' -- counteracts the normal gravitropic
growth in these lateral branches.
We have identified 10 independent gravitropic
suppressor lines that may represent novel genes involved in this function.
Changing the Density of the External Medium Changes the Gravitropic
Response of Rice, Corn and Radish Roots.
Involvement of brassinosteroids in the gravitropic
response of primary root of maize.
However, if they are placed horizontally they will exhibit gravitropic
curvature, which leads to an increase in toughness due to lignification.
response of bean root system to phosphorus deficiency, p.
2000) modelled the gravitropic
effect on root system development and demonstrated that there would be less overlap of P depletion zones around lateral roots in shallower root systems.
In an experimental context we have advanced our technology into several fields, including reproductive physiology, diabetes research, neuroscience, development, gravitropic
responses, ion transport, and bomeostasis.
